Above: Customized EABCO Encore and 1/4" 7-08 Group shot at 100 yds by Keith HudspethWhy We Offer "Accuracy" Barrels...There are three reasons why customers come to us for a custom Encore barrel: The first two are either to get a different chambering or barrel length than what's offered by the TC factory.But the THIRD REASON is to achieve a better potential for accuracy than mass production factory barrels... And, this is why we make our own EABCO "Accuracy" Barrels. Its not magic... just extra attention to the details that result in superior accuracy... Precision Barrel Blanks - An EABCO barrel blank is precision gun drilled from the best Chromoly and Stainless steel alloys. Bore dimensions are reamed consistent to airgauge within .0002" (2/10,000ths) of proper bore dimension. These are then Two-Pass button rifled in the various twist rates we offer to suit particular accuracy requirements. One at Time Barrel Making - True, center-to-center barrel turning at a rate that minimizes stress while keeping the bore in the middle. True, center-to-center chamber reaming insures centering and linear alignment of the chamber with the bore. Each chamber's headspace is checked and confirmed with gauges. True, center-to-center 11° target crown, applied after finishing, insures that bullets exit the barrel with perfectly even gas pressure. Chambers with Accuracy Potential - Cartridges that work well within the TC Encore's capability to handle pressure, bolt thrust, and extraction. It stands to reason that cartridges which operate on the outer edge of a gun's capability will have less accuracy potential than cartridges that operate closer to the gun's sweet spot. The TC Encore has superb potential for accuracy with the cartridges we chamber. We don't do any heavy magnums. † PPC EABCO - Standard chamber that works best with handloads on Lapua brand brass.

Choosing
Your Twist Rate - See More at our Twist Rates Tech Report
We have standards we recommend for various chamberings so you don't have to figure this out yourself. But if you'd like to know some guidelines and reasons, here they are: 17 Caliber: Use 1:9 for the rimfire and centerfires. 22 CF (Centerfire): 1:7 is only for the heaviest bullets. 1:12 shoots 40-50gr bullets accurate in 223 and up to 55gr, accurate in 22-250. 1:14 is only for the lightest bullets. 6mm/.243: Use 1:8 for 90-100gr bullets. 1:10 for 75-85gr. Use 1:12 for lightest bullets (ie. 58gr in 6PPC). On 30 calibers, a 1:10 twist is the best all-around. We DO build a few 30's in 1:8 twists for folks who shoot the heaviest bullets. The rule of thumb with twist rates is this: It is better to err on the side of too fast of a twist than too slow. |
| Eben, I shot this 160 class 10 point on October 17 while hunting at Briarwood Sporting Club in Bellefontaine, Ohio. Once again the 6.5 BRM performed flawless. This buck weighed 236# live weight and he only went 20 yards after the shot. The guide that was with me could not believe how when I hit this huge deer how the 6.5 BRM made him just buckle. The bullet went entirely through the buck and left nothing but devastation in its path. Please feel free to use my picture and story in any of your advertising. Another great hunt, with amazing results from your barrel and cartridge. - Best Regards, Dan McCarthy, Vice President Youngstown Hard Chrome |

What to Consider When Choosing an Accurate CartridgeWith so many choices, folks will often ask what we recommend as the "Best Cartridge". Unfortunately what's best for one situation is not best for another. For example, 6mm PPC has won more Benchrest Shooting Competitions than any other cartridge (I think)... so it should be considered as among the most accurate cartridges in the world. But it's a little light for deer hunting. As a contrast, our 308 Winchester chambering is what the US Rifle team used at the Bisley matches in England... very accurate and powerful enough for deer sized game and larger. BUT, it recoils significantly harder than the 6mm PPC... Making it a more difficult cartridge to shoot well. When recoil gets stiffer, accurate shooting depends more and more heavily on the shooter's marksmanship skill. So, the key to choosing the Best Cartridge for YOU is this: Decide what you're going to use it most for, then choose based on accuracy potential and shootability.Decide What You Are Going to Use it For - If you're primarily wanting to shoot the tightest groups at paper targets, choose 17 Ackley Hornet, 22 Hornet, 222 Remington, 223 Remington, 22 PPC, 219 Donaldson Wasp, 6mm PPC, 6mm Donaldson Wasp, 6mm BR. If you want to use it for Varmint Hunting, any of the above would be fine plus everything else we offer from .17 caliber thru 6mm. For Big Game Hunting, you need a medium to large case capacity with a heavier bullet in calibers from 6mm on up. Be careful here to optimize your choice for what you plan to hunt most often... not for the heaviest game you'll ever hunt. Most good deer cartridges will work just fine for elk hunting when loaded with heavy, bonded core bullets. But, the biggest magnums suitable for elk hunting are usually way too much for deer and a lot harder to shoot well because of recoil. Accuracy Potential - Cartridge Efficiency is something to consider in accuracy choices. If a cartridge is so large that it can't burn all of its powder charge by the time the bullet leaves the barrel, you'll get a lot of muzzle blast for not much increase in velocity and perhaps an accuracy disruption just as the bullet exits the crown of the muzzle. .308 Winchester is more efficient than 30-06 when shooting 150-165 grain bullets. But, 30-06 will give faster velocity potential than .308 when you shoot 180-220 grain bullets. Ackley Improved (AI) cartridges will generally give a boost in both velocity AND accuracy potential due to the bolt thrust reducing body taper. Shootability - Accurate shot placement is more important than velocity, energy, momentum or any other measure of lethality when hunting game. More importantly, it is a measure of your marksmanship that the pure accuracy of your barrel cannot overcome. So, it's important to choose a cartridge you'll feel comfortable enough with that you'll enjoy shooting it... for practice or just plinking for fun. Recoil and muzzle blast are the biggest destroyers of shootability because they cause a shooter to develop bad habits... flinching, jerking the trigger, holding the gun apprehensively, etc. We have muzzle brakes and recoil pads that can help you reduce recoil. As a direct recommendation on cartridges for deer hunting that have moderate recoil and excellent shootability, consider: .243 Winchester, 25-35 Winchester, 257 Roberts, 6.5mm BRM, 6.5X55 Swedish Mauser, 260 Remington, 270 Winchester, 7mm BRM, 7-08 Remington, 30-30 Winchester, 300 BRM, 308 Winchester, and 30-40 Krag. Killing Power for Sport Hunting - There's an excellent article in the P.O. Ackley Handbook Vol I that addresses this from all of the popular viewpoints (energy, momentum, velocity, knock-out, etc.) No one formula predicts perfectly for every cartridge but, what becomes most conclusive toward the end of the article is that being able to hit what you're aiming at is the first priority, followed by the quality of the bullet with respect to penetration and expansion. |

| - by Eben Brown (E. Arthur Brown Co. Inc) The current popularity of 6.5mm cartridges in the USA has been a long time in coming. I won't go into my opinions on why it took so long to catch on... The important thing is that it finally HAS caught on and we're now so fortunate to have a wide selection of 6.5mm cartridges to choose from! 6.5mm Grendel - Developed by Alexander Arms for the AR15 and Military M4 family of rifles. The Grendel fits the dimensional and functional requirements of these rifles while delivering better lethality and downrange performance. There are now similar cartridges from other rifle companies. We chamber for the Les Baer "264 LBC-AR". Designed for velocities of 2400-2500 fps with 123 gr bullets, it shoots the 140 gr at about 2000 fps (for comparison purposes). 6.5mm BRM - Developed by E. Arthur Brown Company, Inc to give "Big Game Performance to Small Framed Rifles"... Namely our Model 97D Rifle, TC Contender, and TC Encore. Velocities of 2400+ fps with 140 gr bullets puts it just under the original 6.5x55 Swede in field performance. 6.5mm x 47 Lapua - Developed by Lapua specifically for long range bench rest shooting competitions. Case capa-city, body taper, shoulder angle, and small rifle primer are all features requested by top international shooters. You can expect velocities of 2500-2600+ with 140 gr bullets. 6.5mm Creedmoor - Developed by Hornady and Creed-moor Sports, the 6.5mm Creedmoor is designed for efficien-cy and function. Its shape reaches high velocities while maintaining standard 308 win pressures and its overall length fits well with 308 win length magazines. You can expect velocities of 2600-2700+ fps with 140 gr bullets |
260
Remington - Developed by Remington to compete with the 6.5mmx55 Swedish
Mauser that was (finally) gaining popularity in 1996. By necking down the
7mm-08 Remington to 6.5mm (.264 cal), the 260 Remington was created. It fit the
same short action bolt actions that fit 308 win, 243 win, 7-08 rem, etc. You can
expect velocities of 2600-2700 fps with 140 gr bullets in the 260 Remington. 6.5mm x 55 Swedish Mauser - The cartridge that started the 6.5mm craze in the USA. Developed by the Mauser corporation back in 1896 (I think), it is famous for having mild recoil, deadly lethality on even the biggest game animals, and superb accuracy potential. Original ballistics were in the 2500 fps range with 140 gr bullets. Nowadays handloaders get 2600-2700+ fps. 6.5mm-284 Norma comes from necking the .284 Win-chester down to .264 caliber. Norma standardized it for commercial ammo sales. The 6.5mm-284 is used extensively for NRA High Power competition at 1,000 yd ranges. Velocities run 3000-3100+ with 140 gr bullets. 264 Winchester Magnum - Developed by Winchester back in 1959, the 264 Win Mag never really caught on and may have delayed the ultimate acceptance of 6.5mm cartridges by US shooters (in my opinion). It missed the whole point and original advantage of 6.5mms. The Original 6.5mm Advantage - The special needs of long range competition have skewed things a little but, the original advantage was in how deadly the 6.5mms are on even the biggest game animals, how little recoil they produce, and how easy they are to shoot well. |
